Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27904, here are decompositions:

3 + 27901 = 27904
11 + 27893 = 27904
53 + 27851 = 27904
101 + 27803 = 27904
113 + 27791 = 27904
131 + 27773 = 27904
137 + 27767 = 27904
167 + 27737 = 27904

Showing the first eight; more decompositions exist.
